It can be lousy style and design exercise to implement a lead screw as equally the driving element and load advice member. The end result is off axis loading of your nut which results in a minute load problem as proven below in Determine 2a. Making use of a second load towards the lead nut can cause quite a few probable failure approaches which includes mounting, PV, and excessive drag.
